SAW FILING GUIBE Filed April 10, 1930 Patented Nov. 24, 1931" THOMAS W. Renon, or SEATTLE, wesrmemon Y SAW ritme GUIDE Application mea Api-i1 io, 1330. l serial ira/143,010.

My invention relates to an improvement in saw tiling` guides, and is more particularly an improvement upon my application `Serial No. 327,016, filed December f 19, 1928, and upon my application Serial No. 860,470, filed May 4, i929. Y

In using'the device of each of my former applications, 'it was necessary for the'saw filer to stand immediately Vaboverthelile, in order that he might keptthe aligner Vbar of the guide properly aligned With the aXis of the tile with Which he Was doing the Work,or else to udge fromexperience Whether or notl the tyvo Were in alignment, `The necessity of standing immediately over the il-eand looking directly dovvn upon it placed the iler inY an unnaturalV and -crampedipositiom but if he assumed a natural stance, at one side of the file and aligner bar, it'became necessary for him to guess at the alignment of the aligner bar and tile, and this to a considerable degree lessened the advantage of the saw iiling guide.

y lt is an object of my presentinvention to provide a means in such savv tiling guide,

whereby the same may be set for the proper angle oi the tile relative to the edge of the saw, and may then be angularly offset fromV such position, so that as the saw filer assumes a natural position at one side of the'lile, he may look towards the ile, 'not directly down upon it, but from the side, and the alignerVV bar will be positionedin such line of sight from the saw filer to the lilo itself, and the filer Will knovv, when he maintains the aligner bar in this line of sight, that the iile is set at the proper angle relative to the edge of the savv.`

My invention comprises the novel parts and present preferred by me.`

Figures 1, 2 and 3 are elevations taken in the direction of the length of the file, showing Y my saw ling guide in three successive positions preparatory to use.

vWhich angular variation ofthe Figure 4 is a side elevation of the Iguide, parts of' the basebeingishovvn yin section.

As in'myformer applications, a basel is provided,` with a socket 10, VWithin whichV isV received a tile F, uponivvhich the base is thus supported, and the base may be firmly secured upon the tile by means of the set screw 11, by meansof which the file andsocketare kept substantially coaxial. Pivo-tallymounted upon thevbase, as for instance, by means at its uppelyend in a horizontal rod 30, Which v isA parallel to the pivotpin and to the axis-,0iE the socket 10, and this Yrodj80rfor1'i'1s apivot indicated at 34," for the supporting link43" of van aligner bare, which bary is maintained parallel to the axis of the socket 10., .llrefer# Y mayA svvingv through Aa path lwhich includes the axis ofthe pivot pin2.l L

plate 5, and theindex ingerflikevvise cor- 'responds with the same Zero mark of'the scale 53. In this position, the aligner bar 4 is in direct vertical alignmentwith the axis of thesocket `10, and asis indicatedby the arrovv, it isnecessary tolook immediately down uponV the aligner ibar 4 to *bring` it4 in` line off sight With theV axisV loit'the'socket 10 y andofthe file F. The two angulari'sidesofff In Figure'l, all parts'are shown intheir i zero position.l The scalef15 coincides fWith-v Vthe Zero mark on the scale'53', carried by the f ,or the pin 2, is an upright 3, which terminates d. the ile are equal with re'spect to a horizontal line.r Y Y Y In Figure 2, the upright 3 has been moved angularly with respect to the plater5 and its index-.finger 33 ,is angularly adjusted relative Vto the AZero point of the scale 53. The yangles ofL the sidesv of therle F have been changed with respect tothehorizonta'lfand -With respect tothe edge of the saw, but nevertheless, in order to bringv the aligner bar A j 4- in the line of sight tol the axis of the file F, it is necessary to look directly down, as is indicated by the arrow A.

In Figure 3 is shown the-final adjustment. The adjustment corresponding to the posif tion of Figure 2 Vhaving previously been made, orv the indeXSSl havingbeen angularly adjusted by an amount which experience has shown to-be desirable, the 'filer now assumes.

a natural stance at one side ofthe file F, and

instead of further adjusting the index VV33, it j is left' at what is known to be the proper angle, and the plate 5 is adjusted angularly with respect to' the base 1 and with respect to the Zero point vof the small scale 15. This *V -action causes'thel aligner bar 4 to swing to oneps'ide ofthe aXisof 'the ile'F and the socket 10, yet nevertheless; it remains in pari allelisin therewith, and'without changing the angle offthesides oftheiile relative to *theV edge'ofthe saw.
